MIT researchers explore method of transferring electricity wirelessly - Wikinews

This is truly news. I've read a lot of Tesla's works, and as soon as I had the time and money, I wanted to try this myself. His ideas were and are revolutionary, and if the MIT folks get this right... well, let's just say, "Hold on to your butts. This is gonna be a ride."

Becoming a Citizen of the Web

It looks as though, due to classes, my geek factor has been suffering of late. I didn't even know what digg or del.icio.us were for until today. Took a look, and man, no wonder they're being used so much. Between these two pages, flickr, skype, slashdot, and facebook, you've got all you ever need for news and to stay connected. Truly, one seems unable to be a "citizen" of the web without having at least a blog and an account on all of these (or similar alternate) services.

Finals

My mom brought me home a sandwich. When she asked me how it was, I responded, "You don't want to ask me anything right now. I'll respond by giving an answer in cartesian coordinates of where it's triggering taste buds on my tongue."
Yesterday I turned a Zip drive into a speaker. Details later.
This week:
Monday: GRE (680V/680M Yay!)
Tuesday: Mathematical Methods in Physics in-class final and Johnny Moseley at Campmor
Wednesday: Work, climbing, and take-home finals in Advanced Mechanics and Electrodynamics (Electricity and Magnetism or E&M to the uninitiated)
Thursday: Differential Equations paper due and in-class final, and Katie comes home!

Who said being a Physics major couldn't be fun?

A December Repreive

Okay, so this blogging has not been going well.
But in the meantime:
- I've managed to become a member of NJSAR
- I've written a few short story bits
- I've run two hiking trips, one an overnighter with stargazing
- I've made the lab at school a little bit less of a mess
- I've applied to grad school (WE ARE... PENN STATE!)
- \lim_{t\rightarrow\infty}{(knowledge(LaTeX))}>>0
(If you can read that last line, you're almost as much of a geek as I am.)
- I've rapelled/abseiled
- I've made a good sized stack of lumber
- I've written yet another publishable paper and done a talk: presentation [PDF]
In short, I've kept myself busy, and even if I didn't build something physical and new every single day, the spirit of that commitment has been kept up.
By the by, I also discovered Piled Higher and Deeper. Read it.

And finally, I got my first issue of Make magazine.

Mission Failure

Well, it seems as though I've failed rather miserably in keeping this blog up to date. However, I'll just put in that I've got a number of projects going on now:
-Optical Logic Gates
-SAR Balloon
-SAR Relay
-SAR APRS
-SAR probability mapping
-Biofuels
-Morse Code-to-Speech for the Disabled
Plus which I've just completed my semester at school, and my Wilderness First Aid course for NJSAR.
Oh, yeah, and I'm finishing my music minor with "The History of Rock and Roll" at school this June.
I'll update as I can, hopefully including some pics from the lab.

Birthday

Yesterday we had a decidedly distracted evening, as Digital Electronics turned into Projectile Motion 101. At the same time I introduced the class to a magnetic velocity multiplier (see movie above), and Dave Russell, our professor, showed us all a vacuum cannon that he'd built to use at the high school he teaches at.
And then there was today, my birthday. A lot of talking on the phone to the Katie was involved, both yesterday and today, and for that I say, "Yay!"
My best present by far was the blackboard, pictured above. As you can tell, I went right to it, working out part of the math for the magnetic velocity multiplier I mentioned before. I find it very interesting that you have to prep the board by rubbing it with chalk and then erasing it so that the first marks on it will not be indellible. I must research that further.

Another Day, Another Demonstration

Another demonstration of physics, my craziness, and stupidity, that is.
The stupidity isn't mine.
The Duke Lacrosse Case is quickly becoming a stormy story of outrage. The stupidity lies herein, but also in the fact that GoDuke.com, the university's athletic department's site, decided to pull the roster of the men's lacrosse team. Why did it still show up on Google's cache, then? [PDF]
Anyhow, I met with Dr. Halpern who showed me his immense boxes of physics demonstration tricks and talked with me about the future of physics teaching.
Then, the big project: this evening I cataloged and catagorized everything that's made it into my SAR pack. The list is here.

Well, Let's See...

What have I been up to?
-Plotting the gravitational field of Saturn and its rings to see if there's some possibility of generating a perspective on gravity quantization from this data.
-Composing yet more music, and being asked to play at a concert at my church, among other things (details to follow).
-School work.
-Designing an amorphous metal-based pressure sensor.
-Reviving part of the trombum as a dijeridoo for Rob.
-Reading far too much Spider Robinson.
-More school work.
-Setting up a vibration-reducing coil housing for my independent study.
-Working at Campmor.
-Teaching myself discrete structures mathematics (since my professor's not doing it).
-Working on the energy audit of my school.
-Still more school work.
-Writing a review paper for my independent study.
-Etc., etc., etc.

Yes, it's been rather busy. I'll post as often as I can.

It's Been a While

And here, for your viewing pleasure, is the most recent circuit I couldn't get to work for electronics class.
In the past week and something since I last made an entry, I've made so many things, such as circuits for my electronics class or a new waltz, or the experimental setup for my independent study, that I don't really know where to begin.
Katie was home last week for spring break, which was absolutely terriffic. We got to spend much more time together than I'd originally expected, which was beauteous. Not only that, but she spoiled me rotten with home-made lunches.
Tomorrow I'm off to Lehigh for the day to see Sir Roger Penrose speak about the universe before (yes, you read that right) the big bang. Link is here.

More Digital Design

I made progress on some file manipulations that I'm doing for Katie today. Also, after working with my digital design professor David "Digital Dave" Russell, (I just had to say that.) I finally figured out how to properly modulate and demodulate the clock signal and data that I'm sending. More to come when I build. As for now, I'm trying (unsuccessfully) to get to bed early so I can get to school early and work on Discrete Structures review for my test on Friday. Yeesh!

In the Last Week...

In the last week, I've definitely been busier than I've been since the beginning of the semester, or maybe even since the beginning of this school year. At the same time, I've been making a lot of stuff. I've been working on the experimental setup for my independent study, composing some new music, and creating a lot of interesting circuits for my digital design class.
I also have to make myself ready, this week, for two tests: Discrete Structures and Multivariable Calculus.
In other news, the quote that started a new game was put up by my friend Pete Oliver as an away message:
You're driving down the road, and you stop at a red light. The archbishop pulls up beside you, and rolls down his window. He asks: "Pardon me, do you have any Grey Poupon?" You hand him a jar from your glove compartment, and he spreads some on a communion wafer. As he bites into it, you wake up screaming, and your pillow is missing.
My friend Pete HDP (the OTHER Pete) and I started making this into a very weird Mad-Libs. He said he'd post some of the ones he came up with, so a link will be up shortly to that.

Teodorian Natural Philosophy

I'm in the process of trying to revive the physics club at school which, unfortunately, has been ailing of late. I got defaulted into the position of VP late last semester. So far, we've got an ambitious list of people we'd like to bring to speak, and a slowly growing new set of by-laws. So, that's what I've made today, other than a proposal to create a unique area at school for the science majors to hang out in. More to come as my insane schedule allows.

Oooh! Shiny!

Wow. Check this out. Multi-Touch Interaction is quite a neat field. Now I'm working on something similar: on the proto board I have for my digital design class, I'm working out a simple LED/photodiode switch to use instead of the on-board buttons we have. Pictures to follow.

Finally I Get Back...

Well, I'm back in the saddle again. This past week has been quite a whirlwind. I had quite a bit to do for school, and also some extraneous projects such as certain musical ones. I had Valentine's Day gifts to get for Katie... In short, quite a lot to do.
As for music, I'll put up a post on that soon. Needless to say, most of the things I've been making are assignments for school.
Also, I've made a change at Campmor: I'm now working in tents most of the time, as of this past wednesday.
In other news, this past tuesday I had an interesting hydrogen-roadmap fuel cell-related symposium to sit in and take notes on. More news and a link on that later, though.
And now back to schoolwork.

Nrrr... Nrrr... Chili

Pete's Chili Fresca

2-2.5 lbs. ground turkey (or ground beef)
.5 lbs. sliced turkey
3 Holland peppers
2 frying peppers
3 Carib Chili Peppers
2-5 Habañero or Jalapeño Peppers to taste
2 tbsp. olive oil
1 can (19 oz.) black beans (drained)
1 can (15 oz.) red kidney beans (drained)
2 cans (16 oz. each) diced tomatoes (drained)
3 limes
4 cloves garlic
2 tsp. Cumin
3 tsp. Paprika
2 tsp. Oregano
2 tsp. fresh ground Pepper
4 tsp. chopped Cilantro (optional)

First wash and chop all peppers. Put these in a large bowl and mix. Juice 2 of the 3 limes over this mixture. Peel the garlic, and crush it under a fork. Place this in with the peppers. Juice the remaining lime over the pepper mixture. Chop 1 of the 3 onions and combine with the peppers. Mix thoroughly with clean hands, squeezing together all peppers and coating all of the mixture with the lime juice. Chop the remaining two onions finely, and add with the olive oil and ground turkey to a large pan. Brown the turkey, then add tomatoes, red kidney beans, and black beans. Slice sliced turkey into small strips and add to meat. Now add the pepper mixture. If using Cilantro, add it now. Mix Cumin, Paprika, ground Pepper, and Oregano in a small bowl, and add to the full mix. Simmer for 10 minutes, stirring every 2.5 minutes. After 10-15 minutes, transfer mixture to a crock pot. Cook on high for 30 minutes. Turn heat to low, and simmer for 7.5-8 hours.

I brought this to church this morning for the Chili Cook-Off, and wound up winning a bottle of Merlot. That I gave to my parents: I don't drink.

TTL

Here's the diagram of that XOR design I was talking about. Note also that the two not gates (the single-transistor ones) in the bottom left corner are slightly reversed, as the output lead should be on the top, rather than the bottom, of the gate.
Otherwise, yesterday was work, work, work. Then I fell asleep watching Grizzly Man on the Discovery Channel. Great film if you get the chance to see it.
Well, today's work, work, work again, and then make chili in the evening.

School Begins

Well, I may have to tune down my expectations for what I can do postwise during the semester. As for what I've made:
Monday I composed a new piece for the piano amidst the first day of classes.
Tuesday I was the first person to make a counter chip work in my digital electronics class.
Wednesday I made an even better counter on my off-class time, and got two of them working in parallel.
Today I figured out and planned an NPN-transistor only version of an XOR gate. Talk about using what you know! I used my knowledge from my discrete structures class to figure the logic, and I used my electronics knowledge to create the real design.
I don't know when I'll be able to post next, but hopefully it'll be tomorrow.

Biofuel Blowout

Well then!
Thursday morning I left for Troy's with my dad. We got up to Masonville, NY, and found Troy. It wasn't too long before we were down in the basement of one of the houses he owns, putting together plans for a WVO reprocessing system to be used with his oil furnace. With us were Troy's son Vaughn, a welder and car mechanic, Gary, an electrician/hvac tech/plumber, and Alex, a semi-retired manufacturing engineer. We were somewhat stymied by the whole filtering aspect of production, but we continued on, working on a 5:1 WVO/methanol mix which we found that evening to be quite good for our purposes.
I've also found out that Troy wants to do biofuels in a big way. As he says it, "I wanna F**K an oil company!" Much of the knowledge I gained from this visit was useful in deciding how to do that, such as that there are many people in the Delaware County region of New York who are currently farming Canola specifically for use as an oil fuel source.
So that's what took up Thursday and Friday. Yesterday, Saturday, I had work all day, and then my parents arrived back from Masonville that night. Later, I had the hard task of going through plans and articles online to see what the cheapest, easiest way of making biodiesel from WVO might be. This site has some of the best information out there.
And now to make the filtration system plans...

There's a Printer in the Car!

Let me repeat that sentence, because it bears repeating. There is a printer in my dad's car. Hooked up to the cigarette lighter port, we have an inverter. There is a splitter on that, which hooks to my laptop and, yes, the printer in the back seat. Also, today I made an estimate on the burn temperature of an alcohol/oil mixture, and proved that such a mixture would work as a fuel. All in all, a very busy day. I can't wait to get up to Troy's tomorrow!

Craft Day

Today was a day of craft projects. I made a lantern out of some tissue-paper mache, some wire, and an old LED bottle opener. I also started in on making the beads that I intend to sell next month. all of them are rolled paper. I also got a bit more done on my website.

And don't worry. Tomorrow I promise I'll make something a bit more... interesting.

The Site's Up!

Today has been a productive day. Unfortunately, when I woke up this morning, it was to sleet and snow, and as I told Katie on the phone, there's no way I'm driving three hours into New York state in that. No siree Bob. So, I was forced to be productive at home, instead. Now there's a new website for me to show for it: petmar@physics.ramapo.edu. Check it out! It's what I made today!

Still in Limbo...

I still don't know if I'm heading upstate to Troy's tomorrow. I will find out in the morning when I look out the window and see what kind of mess the weather has made.
Speaking of making things, I made a good bit of music today with my friend Rob, and we also got to talking about RONJA. Thanks to a VGA connector pinout, we were able to figure out how to make a multichannel optical link for a high-bandwidth low-loss remote monitor, via either fiber or air optics. You can see the basic layout above.

Cooking Again...

Due to work and my parents' anniversary dinner today, the only thing I made, other than a few shoe sales, was breakfast. At that, I only really helped make it.
Also, today I discovered RONJA, Reasonable Optical Near Joint Access. Watch this space for more development of RONJA repeaters and RRNA (Reasonable Radio Network Access) projects. This seems like a cool project to jump in on.

Water Sensor, Take 2

Sorry about yesterday. I spent the day with my parents and my Grandma, and had a good time.
Anyhow, today so far consisted of a lot of running around. My parents are very enthused about the water sensor, and so I've created the full-scale production model, which will be placed up in the basement ceiling, under the bathroom tub. Hooray!
My favorite part of this is the tensioning method I used. There are three little blocks holding wires that connect to the upper electrode: the screen. These are taught, and so suspend the screen above the metal contact plate.

Infinities

Today included a goodly bit of hanging around, waiting for the weather to clear up. It didn't till the afternoon, so I worked on previewing some of the material we'll be doing in my multivariable calculus class. I also worked further on my newest piano composition, and made a Möbius chain, as you can see above. Yes, each of those little links is a Möbius strip. Fun, eh?

Water Sensor

Well, yesterday my dad and I took down a panel on the basement ceiling due to an apparent leak above it. Above you see my solution to the problem: a prototype water sensor that will light an LED when more than a drop or two of water is on it.

The Makings of a Meal

Today, I composed another song, made a commitment for tomorrow, and made dinner.
Dinner was tortellini with creamy garlic-marinara sauce, chicken with spinach and provolone, and a caesar salad. The new song, well, I'll probably upload a midi of that tomorrow. And the commitment is to take Katie's brother Matt down to school tomorrow. 9a we begin the road trip!

Dry Ice

We got some ice cream today, and they packed it in with dry ice.
Obviously, when I got home, this meant time for fun. I first dropped
some in a cup of water and got that to bubble and fog. But then an
idea hit me: I put some in a used spring water sport bottle, and let
the pressure build up until the valve on top popped. Hmm... releasing
gases... That's when I put the drip of dish detergent into the cup.
Sure enough, a column of foggy bubbles began spilling over the edge
in what one might call a stable foam. I then put a drop or two in the
sport bottle, as you see there above. Quite fun!

Friday's Fun

With all my running around today, I can say that I still got to make something: a mess. Yeah, I know. I barely have time to do this post, and I'm not certain if I'll be able to do one tomorrow.

More Google Earth...

More fun with Google Earth...
The first one up there is a double overlay of a topographical map and hi-res aerial photo of a piece of real estate that my parents are looking at purchasing.
The next one is from a fun little project I did at school, the Drewcam. I overlaid the field of view (FOV) image onto the Google Earth landscape, and was able to profile the geographic features that you can see in the camera's view.
Finally, the last one is a map that my dad and I have been working from of Little Ferry Farm in the 1870s. This approximates the area where the supposed nitroglycerine blast was.
Neat stuff, eh? I've really gotta start working on making physical things again, though...
Although, I will say that my friend Terry's power supply project might afford that opportunity. Updates on that as events warrant.

Ah, Wednesday...

And Katie's home from Costa Rica! Lots of running around today, and the only thing I got to make was a friend: Google Earth is out for Macintosh!!! Woohoo!!!
Oh, and Katie and her folks loved the pie. Oh, happy day!

Mmm... Pie...

Today saw me make a weird scheduling lapse. I thought my girlfriend was coming home from Costa Rica today, but, instead, she's coming in tomorrow. Not much of a big deal there, with the exception that I was running around tracking flights all day for nought.
Anyhow, she's a big fan of cherry pie. To be precise, a fabulous version of it wherein tapioca is used instead of corn starch as the thickening agent. She's used this pie to "accidentally" ruin me to all other cherry pies. Well, as her welcome-back-present, I've baked her one such pie, the first I've ever made. Let's see how it goes over tomorrow...

A fool...

Today, well, today was spent working on things around the house, and with helping my dad with some research. We're working on figuring out the case of a nitroglycerine explosion in the 1870s down in Little Ferry, NJ. We've made a good bit of progress. Also, today saw me make a fool of myself while trying on a renfaire costume my friend Rob had put together. Picture to come later.

Tracks...

I know it sounds lame, but that's what I made today. I made tracks across the Anthony Wayne Recreation Area with the rest of the NJSAR crew. Afterwards it was come home and laze about time.

Par-tay

Well, the thing I made today was music. I was out at the Campmor holiday party tonight, being one of the few people who were not drunk off their butts by the time they left. I have to get to bed, as tomorrow morning at 8.30 I've got a SAR drill.

Four Words...

Digital
Camera
Not
Working

Grrr...

In the meantime, I've been working on making the backpack fully complete, and with the addition of clips and such for my radio, GPS, and cell phone, I think I've got the makings of my full nav/com package, along with room for a backpacking tent and sleeping bag, if not a ridge-rest or therm-a-rest. I've even got a pillow in there! My SAR bag is ready, and, I think, so am I. Now I just have to be sure to pick up my maps and Bryan's gaiters at work tomorrow...

And yes, that's what I made today: modifications to my backpack.

What time does the penguin on top of the telly explode?

Eight o'clock.
Intercourse the penguin!

I spent a good bit of today making up and packing my kit for the search and rescue drill I'll be doing with NJSAR on Sunday. We'll be hiking around Anthony Wayne for a while (i.e. 7 miles). I went in to work this evening to find that I wasn't actually scheduled, and found I'd been reading my co-worker Matt's schedule, a line below mine. They let me stay the four hours to re-organize the Books and Maps section, anyway.
I'm reading another great book, now that I'm done with The Know-it-All: Spider Robinson's Callahan's Key. A fabulous read. I just regret not reading the other books in the series first, but this just looked too interesting at the Ridgewood library to pass up, and they didn't have any others from the series.
Apologies for no pictures; further updates as events warrant...

White LED Interlude

Let me start by remarking that if you're ever in the northern Bergen County, NJ area and need some sort of small electronic part, you should really head on over to the Radio Shack in Midland Park. They actually know what the heck they're talking about over there! The fellow who helped me find the white LEDs actually made certain I had a resistor to put in front of the LED so that I wouldn't toast it! Needless to say, I was impressed. Every other Radio Shack I've been to recently would rather sell me a cell phone than help me find a 2N2222 transistor that I'd asked for. Highly inappropriate. As I was about to leave, the guy said that he guessed he'd see me back there again. I told him that when I needed parts, I'd know where to go.
Speaking of northern Bergen County, the Ridgewood Public Library has recently undergone an extensive renovation. If you get a chance, go have a look-see. It's beautiful!
But about today's project...
Last night my parents and I had a wonderful visit with our next-door neighbors, Fred and Jane. Fred showed us a splendid 3-D woodcut that he'd gotten from Germany. It was laser-cut wood. We were all duly impressed. Fred then told us of the one thing that was missing: there'd been a light hanging from the top and illuminating the inside. He then showed us the light, a rather heavy-handed affair, looking for all the world like a nightlight from the 1970s. For all we know that's what it might have originally been. We decided a small white LED lamp might look better after I demonstrated how it would look with my LED penlight. And so, I was commissioned to build one. That's what I made today, as you can see above. I happened to have an old power indicator LED PC board from an old computer laying around, which made things easier. I drilled a .25" hole for the switch, and connected the LED, switch, and 2xAAA battery box.
Ét violá!

It's Being Framed!

Yesterday I saw The Lion, The Witch, and The Wardrobe. Go see it, you won't regret it. My friends Rob and Pete were discussing the allegories and allusions to Christianity and Christian mysticism in the story. They missed so many of them that it's not even funny. It really isn't! As for today...
Well, today was a day for sitting around, doing a couple of things that had to get done, and most of all, working on my newest project: converting an old travel alarm clock/calendar/calculator to a new housing. What new housing? A picture frame. To be precise, I'll be using the extremely postmodern-looking CLIPS frame from Ikea. I've still got more soldering to do, so it'll probably be done tomorrow.

A Link...

You must go to this site. This webcomic is just my speed. As a Mac user who's also an amateur inventor of sorts, I positively love what they're doing. Check out the archives, and you'll see what I mean.

Trombum? Drumbone?

What should I call this thing? It's a tunable drum that works like a trombone.
Last night I had a bit of a party over at my house, and in the midst of it all, my friend Nick and I got to talking about Potato Guns, the US winning the space race, and other fun stuff. That's when the PVC pipe came out of the back room.
Now, a word about my parties. They are dry. That is to say there's no alcohol involved whatsoever. We're all crazy enough, though, so some really weird things get done, said, and, as you can see here, made.
The PVC pipe in question was sitting in my workshop, just the other side of the wall from the room in my basement that we were having the party in. Next came the tubing and the duct tape. By the time that Nick had left and it was down to just three of us, I had a funnel involved. I asked my friend Joe what he thought I could do with this, and he merely shrugged. Tape over the funnel provided a handy drumhead, and some duct tape on the slider pipe made for a slightly better seal.
I already had a fixed length pipe (see the first picture above) to shove in the end with a pretty good seal, and viola! The drumbone, trombum, trum, or whatever you'd call it, was born.
Hear it in action!

My First Mechanism

Yes, that's a clock movement.
I've unbuilt and reassembled this one.
The interesting thing about this is the part that you don't see. Somehow, in my variously well-spent youth of dissasembling small household items, I never got around to a quartz clock movement. Let me tell you, it's been an experience. The gears are tiny, and the motor isn't so much a motor as a solenoid with a magnetic bead between the poles. It's amazing how it works!

What I did:
I took apart and reassembled the movement (technically cheating, since I did it last year, i.e. 3 days ago). I then put the small ball-chain on the minute hand part of the crown assembly, and put the zip tie on the hour hand part of the crown assembly. I then put the copper 12-hour reset delimiter wire on. This can now act as either a variable minute or variable hour timer, and can either pull something with the chain, or switch something with a wire glued to the zip tie. Ladies and gentlemen, a mechanical timer, for your viewing pleasure.

What I'm getting myself into...

So this is my new year's resolution list, in order of importance:
-Work harder in my courses.
-Write a blogger journal every day.
-Make something new (or work on making something new) every day.

 To explain a little bit, I'm taking somewhere around 20 credits worth of courses at Ramapo College as a Physics major. As for the journal, I've started so many notebooks and journals that it's ridiculous how few are filled completely. Actually, the first time I ever completely filled a notebook was this past semester in my Calculus 2 class. How sad is that? I figure what with being able to e-mail blog entries to myself, I should be more than able to work through my apparent lack of attention to notes.
 Recently I've been reading the book, The Know-It-All by A. J. Jacobs, wherein the Esquire editor decides to read the entire Encyclopaedia Brittanica, and it has inspired me to make some sort of quest for myself. This year will hopefully see me make some very cool things, and some interesting journal entries in the meantime.
 Now, I understand that there are some very easy cop-outs (oh, how I loathe that phrase...) that I could make here, and I intend to, whenever possible, avoid them. So, some ground rules:
-The thing that I'm making may not have schoolwork as its primary purpose.
-Only a restriction of access to both e-mail and web can justify a lack of entry for a day. However, if I get access, I must do a backdated entry.
-Finals and important assignments for school or my internship take precedence over writing or making something. That being said, backdated entries are still okay.

Wish me luck!
